What is the solution for fuel tank noise in Ford Kuga?

Ford Kuga fuel tank cap noise requires inspection. If there is a whining sound, it indicates that the carbon canister connected above the fuel tank may be blocked or there may be a design defect. To avoid bigger problems, timely repairs should be conducted at the relevant manufacturer.
My Ford Escape had a fuel tank noise issue before, that annoying gurgling sound was really irritating. I took it to the dealership for inspection, and the technician said it was caused by a loose fuel level float inside the tank, most noticeable when the tank was half full. They opened up the tank to resecure the float bracket and added soundproofing foam to the tank exterior, which significantly reduced the noise. I heard that some model years of the Escape had fuel tank design flaws, and Ford even issued a technical service bulletin allowing free replacement of the improved tank bracket. If it's out of warranty, DIY solutions aren't difficult - check for cracks at the fuel pump mounting points, ensure the tank strap bolts are tight, and applying $20 worth of vibration damping adhesive to the tank exterior works surprisingly well too.
When encountering abnormal fuel tank noises, the first step is to identify the sound type—some are caused by fuel sloshing while others result from metal collisions. In my last case, it was a suction sound due to a clogged charcoal canister, which was resolved by replacing it. The Ford Kuga's fuel tank has a relatively flat design, making it prone to fuel sloshing when low. Recommended inspection sequence: maintain fuel level at three-quarters to observe sound changes, check if the fuel tank straps are loose, monitor the charcoal canister solenoid valve for abnormal vibrations during operation, and finally inspect the fuel pump bracket for cracks. For those with mechanical skills, tightening the fuel tank straps using a torque wrench to 30 N·m is manageable. These parts are available as aftermarket components in auto parts markets at half the cost of dealership prices.
